A Contemporary Framework Key Based Crypto Method to Enhance Security in Multi Cloud Ambience

Cloud Computing, similitude of Internet is a technological amelioration which is in regime for last two decades because of its Pay-per-Usage policy. Despite its multitudinous benefits, particular aspect which is shuddering its wider adoption throughout the technological society is its Security. In this paper, proposed a security framework Modified Key Based Crypto Method (KBCM) which is an amalgam of Improved Hamming weight-based RSA and Shamir Secret Sharing Scheme. KBCM is designed and implemented such that is enhances the security of data by assuring Confidentiality, Integrity, Availability (CIA) in multi cloud ambiance.
